I see something like this:
require "ostruct"
class OptionsWrapper < OpenStruct
undef :id, :class
def [](key)
send(key)
end
def []=(key, value)
send("#{key}=", value)
end
def method_missing(method, *args, &block)
return @table.include?(method) ? @table.send(method) : nil if
%w(id class).include?(method.to_s)
@table.respond_to?(method) ? @table.send(method, *args, &block) :
super
end
end
I know OpenStruct is a class part of standard ruby library allowing
you to arbitrarily create methods on an object instance. I know that
undef allows you to set a method to nil. But I dont see why it is
needed in this case.
thanks for response
